Human activities have severely altered the Yangtze River (Changjiang) Estuary’s pattern, beach-trough shape, and delta in recent decades. Existing research has studied sediment “source–sink” relationship between mainstream estuary using gauged suspended data. This method overestimated decline concentration estuary, as riverbed scouring or deposition not filtered out amounts related to sand mini...

Biocorrosion is a phenomenon that strongly affects the integrity of materials used in oil and gas industry. Different types biocides are currently to control bacteria industrial water; however, they have disadvantages such as microbial resistance these chemical compounds possible impact on biodiversity due eventual contamination natural water. There several alternatives for elimination or bacte...

Agricultural soils undergo periods of saturation followed by desiccation throughout the course a growing season. It is believed that these wetting and drying influence soil structure may affect rate detachment. Thus, an experiment was conducted to investigate disturbed (soil sieved simulate tillage) subjected various cycles, on bulk density resistance detachment with runoff. Seven treatments co...

There is more diversity among microorganisms such as bacteria than there is in the range of life from artichokes to zebras. Bacteria have successfully colonized virtually e very environment on earth because they can rapidly adapt to changing conditions, and use a large and varied number of nutrients to generate energy. How e ve r, until relat ively recently, the environments of many petroleum r...

While demands on video traffic over mobile networks have been souring, the wireless link capacity cannot keep up with the traffic demand. The gap between the traffic demand and the link capacity, along with time-varying link conditions, results in poor service quality of video streaming over mobile networks such as long buffering time and intermittent disruptions. Leveraging the cloud computing...

A large amount of intellectual effort is expended every day in the play of on-line games. It would be extremely valuable if one could create a system to harness this intellectual effort for practical purposes. In this paper, we discuss a new crowd-sourced, on-line game, called Ghost Map that presents players with arcade-style puzzles to solve. The puzzles in Ghost Map are generated from a forma...

The fermentation of cabbage is a spontaneous one, and the manufacturer of sauerkraut must take the undesirable microorganisms along with the desirable ones. Because of this chance inoculation, there is a wide variation in the quality of sauerkraut. A large variety of organisms is introduced with the green plant tissue when this is placed in the vats. Many of the forms on plants can not survive ...

There is considerable loss of DM during wet heat treatment of vegetables, leading to an increase in dietary fibre. Correction for the loss of DM indicates that the effects on total dietary fibre are minor. There is, however, depolymerization of the dietary fibre polysaccharides. The degradation is related to the severity of the heat treatment. Souring, freezing and mild microwave treatment have...

Microbial activity associated with produced water from hydraulic fracturing operations can lead to gas souring and corrosion of carbon-steel equipment. We examined the microbial ecology of produced water and the prospective role of the prevalent microorganisms in corrosion in a gas production field in the Barnett Shale. The microbial community was mainly composed of halophilic, sulfidogenic bac...

Ghale-madreseh is the first point that the saline and sulfurous streams flow into Tembi River, one of the well-known saline rivers in Khuzestan province, Iran. This river is one of the main sources of increasing Karun River’s salinity, which is the largest river in Iran in terms of discharge. There are three saline and sulfurous springs (Shour-1, Shour-2m and Namak Springs) as well as a drinkab...
